I have not tried it yet, as I am afraid, because I have realised that I do not have my CD that came with my webcam so if they want me to uninstall the whole thing and reinstall, then I am buggered so just let me find out from my nephew first before, i try
something and then ending up having to buy a new webcam

It is very unlikely that the new driver will fail but ther are acouple of things you can do to get your old driver back.

If you make a System Restore point before installing the new driver, you can always do a System Restore back to the same point if the new driver doesn't work out.

Alternatively, you can open Device Manager with the web cam plugged in, navigate and expand imaging devices, double click on Microsoft web cam, and select properties. Click on the driver tab and the click on the roll back driver button.

Sorry for just jumping in but I am starting to get confused over this Windows 7 and the Microsoft Life Cam VX6000 topic. I have only had Windows 7, (Ultimate, Home, Professional)on only HP Computers for at least the last 10 years, and I have had this
same webcam that I seldom use, but I have plugged it in and have taken selfies with it for my Mom from time to time over the years.

My last HP Desktop with Win 7 sort of blew up a few months ago so I purchased a refurbished HP Desktop, again, with one of the versions of Windows 7. I had my I had most of my files on the prior hard drive transferred to this newer computer's hard
drive. I have the Life Cam Help topics still loaded and the app comes on my monitor, but now it says it cannot see a camera on this computer when I plug in the LifeCam VX 6000 webcam. To be fair the light on the Webcam does not come on, but I
thought that was because I was missing a file or something as I have had so many niggling little problems lately due to some updates, so I just thought I should download the whole shootin' match again, since I don't know how to find that one file or driver.

My point is, Windows 7 and the Life Cam VX-6000 have worked together for me for many years and I have the pictures I took with it that prove that, hence, the cruxt of my confusion here. I am unable to utilize the link uploaded by Rainier now, however.
The link takes me to a Microsoft webpage that has Oops!! in very big letters saying it can't find what I am looking for.

I looked for the properties to the Microsoft Life Cam that IS still installed on my Win 7 64 bit programming and it shows the .exe file. I thought I might try that to see if the driver might download again.
